最近由于在做一个实验需要搭建一套10G RAC环境，采用了 VMWARE 的方式，大家知道oracle rac是需要准备共享存储的，关于ocr和vote disk盘在节点1上进行分区后，然后进行绑定，执行 service rawdevices restart 可以看到绑定的设备。
[root@amto04 ~]# service rawdevices restartAssigning devices: /dev/raw/raw1 --> /dev/sdb1/dev/raw/raw1: bound to major 8, minor 17 /dev/raw/raw2 --> /dev/sdc1/dev/raw/raw2: bound to major 8, minor 33 /dev/raw/raw3 --> /dev/sdd1/dev/raw/raw3: bound to major 8, minor 49 /dev/raw/raw4 --> /dev/sde1/dev/raw/raw4: bound to major 8, minor 65 /dev/raw/raw5 --> /dev/sdf1/dev/raw/raw5: bound to major 8, minor 81done
然后我在节点2，执行serivce rawdevices restart命令：
[root@amto05 ~]# service rawdevices restartAssigning devices: /dev/raw/raw1 --> /dev/sdb1/dev/raw/raw1: bound to major 8, minor 17 /dev/raw/raw2 --> /dev/sdc1Cannot locate block device '/dev/sdc1' (No such file or directory) /dev/raw/raw3 --> /dev/sdd1Cannot locate block device '/dev/sdd1' (No such file or directory) /dev/raw/raw4 --> /dev/sde1Cannot locate block device '/dev/sde1' (No such file or directory) /dev/raw/raw5 --> /dev/sdf1/dev/raw/raw5: bound to major 8, minor 81done
sdc1,sdd1,sde1 三块盘绑定的有问题，通过fdisk是可以看得到的。
此时需要通过在节点2 执行 partprobe 命令即可。
[root@amto05 ~]# partprobe[root@amto05 ~]# service rawdevices restartAssigning devices: /dev/raw/raw1 --> /dev/sdb1/dev/raw/raw1: bound to major 8, minor 17 /dev/raw/raw2 --> /dev/sdc1/dev/raw/raw2: bound to major 8, minor 33 /dev/raw/raw3 --> /dev/sdd1/dev/raw/raw3: bound to major 8, minor 49 /dev/raw/raw4 --> /dev/sde1/dev/raw/raw4: bound to major 8, minor 65 /dev/raw/raw5 --> /dev/sdf1/dev/raw/raw5: bound to major 8, minor 81done
